Thisvinvention relates-to metal weatlfierfY Vstrips for .windows equippedwith sliding sashes, .and is an improvement on thezmetal weatherstrip shown in my Patent, No'.1,219,' 009.,.dated,March,13, 191,7., The invention has for its principal obj eets to preserve all 4of.,

the advantages of the above strip anduatthe same time to increase` its -weatherproofing qualities and to obtain other advantages hereinafter appearing. rl`he invention consists in the improved weatherstrip, and inthe con-v struction, combinations andarrangements of parts hereinafter described and claimed.

. In the accompanying drawing, which y fforms part of ythis specification and wherein like symbols Arefer to like parts wherever they occur, l Y .Y A

Fig. 1 is a fragmentary horizontal 'cross-v section through one yside of awindow pro vided with a .metal weatherstrifp embodying myv invention, f'

Fig.V 2 is lan enlarged horizontal cross-secy ae tion through the cooperating portions ofthe sash and frame members of said weatherstrip and the parts of the window located adj acent, thereto,

yF ig. 8 is a perspective view of the sash member of said weatherstrip; andl Y Fig. 4 is a similar'view of the frame member of said weatherstrip. Y Referring to the accompanying drawing, a portion of the casing or jamb member 1 of an ordinary window .frame is shown as ar-` ranged for vertical sliding sash 2,`the respec# tive walls of .the vertical slideway for said sash being formed by a parting strip Briand a stop member or molding 1. v The sash is rabbeted, as at 5, along the vertical corner there, of located adjacent toV the parting strip V3 to accommodate the slidably interloclred portions of sash and frame members Av and B, respectively, of a metal weatherstrip.v f The :present weatherstrip comprises' cooperating strips A and B of sheet metal gap of the groove opening toward theparting4 stripuguV One marginal portion of the sash stripextends laterally from one side of they mouth or gap of the beaded groove portion 6 in the form ot a flange 7 that isrigidly lsecured flatwise, as at 8, to the adjacent side face of the sash, and the opposite marginal portion of saidstrip is-doubled back, as at 9, along theouter face of said beaded groove portion to form a stiff, rounded edge along the opposite side of the mouth thereof. i Y

The frame strip B is relatively flexiblev and comprises a'wide flange 10, which is located betweentheopposingvfaces of the sash and jamb and is rigidly secured along one marginal portion ot' said amb,`as at 11,preferably under the stop or molding 4. The opposite free marginal portion of the vwide flexible flange 10 of the j amb strip is curved or bent laterally, as at 1 2, toward the sash and is thence rebent or looped to provide an under cut longitudinal bead or hollow rib 13 of sub.- stantially circular shape in cross-section adapted to lit within and be slidably engaged by the beaded groove portion 6 of the sash strip A. The walls o1 thebead 18 oftheframe strip B are brought together tlatwise, as at 15, to fit the mouth of the beaded groove portion 6 of the sash strip A.; and the frame strip is thence bent laterally of the rib 13, as at 16, so as to overlap the adjacent portion of the flange 7 of said sash strip and is thence doubled back upon the portion 16 to provide a flange 17. ',The flange 17 works loosely in a Vertical groove 18 provided therefor in the j amb member of the window frame. In practice the marginal portion 19 of the wide liange l0 of the frame strip is bent at an oblique angle, whereby said portion is adapted to press firmly against the face of the j amb when the strip is nailed thereto.

The hereinbefore described arrangement provides a full floating, freely. slidable, interlockingjoint between the sash and frame member of the` weatherstrip which permits the sash to move horizontally to and from the frame and to tilt therein without disturbing the joint, such movement being permitted by the flexibility of the frame strip. It is noted as animportant advantage of my invention k backnpon theouter face of thebeaded groove r'portion 6 thereof and'thus cooperates with that the flange 9 ofthe sash strip isv doubled the curved portion 12 of the exible flange l0 of the frame strip some distance from its "edge,thereby preventing said edge from cilt'-l ting the frame strip. V'It is alsonotedthat the .concavezsurface of thecurved portion 12-of i T :Whatlelainiisz' f the frame strip..serves to prevent spreading Yof lthe:beaded grooveportion Gof-thesaSh j strlp'g'and italso serves as a cani orguidefo'r forcing the double backedge 9 ofsaid beaded vgroove portion into engagementvvith the nar-U f'roW neck portion l5 of the bead 130iv the sash strip afterl vthevend portion thereof has been snapped over the bead member*13;` 'of the.
